Common presentation: wheeze
Wheeze is a breath sound that is
heard during expiration. It is often associated with prolongation of the
expiratory phase of the breathing cycle. Wheeze indicates obstruction to
airflow within the thorax. It can be high- or low-pitched; this differentiation
indicates that the obstruction is likely to be in the smaller and larger
airways, respectively. Also, wheezes can be monophonic or polyphonic;
identifying these sounds will tell you whether the obstruction is likely to be
in one or multiple airways.
